What the formula actually does

Read from the label, not the marketing

Each row says where it comes from: F means we derived it from this product’s own ingredient list, S means it is a claim the brand makes that the formula neither confirms nor contradicts.

Weight on the hair Medium

Middle of the range — noticeable on fine hair, light on coarse hair.

Slip and detangling High

Conditioning agents sit high in the list — this is a detangling formula.

Water-binding (humectants) Moderate

Humectants in the working part of the formula.

Oils and butters None

No oils or butters in the list.

Protein None

No protein or amino acids in the list.

Needs detergent to remove Yes

Water-insoluble silicones or waxes: a detergent wash is what removes them.

Fragrance Present

Fragrance is listed; it sits below the working ingredients.

Ingredients that matter

The ingredients that change a decision

The workhorse ingredients plus anything lower down that changes a decision. These chips name what an ingredient does — they are not safety scores, and no ingredient here is rated good or bad on its own.

Full ingredient list (26)

US labelling rules put ingredients above 1% in descending order of amount; below 1% they may be listed in any order. Annotations keep three readings separate: the ingredient's general function, its role in this product type, and what its position can support.

1 Water · Aqua/Water/Eau

General function
The base of almost every rinse-off and cream hair product. It carries everything else and is normally the first ingredient on the label.

Leading ingredient
Listed in the first three ingredients, it is likely a structural part of this formula.
- solvent
2 Isopropyl Myristate

General function
A very light ester that makes products glide and disappear quickly on the hair.

Leading ingredient
Listed in the first three ingredients, it is likely a structural part of this formula.

May suitFine or easily flattened hair
A light emollient: it softens the surface with noticeably less weight than an oil or a butter.

May suitFrizz-prone, damaged, or high-friction hair
Spreads thin and lowers friction between strands without the heaviness of a fixed oil.

PubChem
- light ester
- emollient
3 Dimethicone

General function
The most common conditioning silicone. It coats the strand for shine, slip, and frizz control, and needs a detergent (not just water) to wash out.

Leading ingredient
Listed in the first three ingredients, it is likely a structural part of this formula.

May suitClimate-sensitive or frizz-prone hair
A surface film slows how quickly humidity reaches the cortex, which is what limits swelling-driven frizz in damp air.

May suitFrizz-prone, damaged, or high-friction hair
Lays a smooth film along the cuticle, which lowers combing friction and flattens the surface irregularities that read as frizz.

May not suitBuild-up-sensitive routines
Dimethicone does not disperse in water. On a routine that skips detergent it stays on the hair and accumulates wash after wash.
- silicone
- emollient
- conditioning agent
4 Amodimethicone

General function
A silicone modified to stick where hair is damaged, so it smooths selectively instead of coating everything. It resists rinsing more than plain dimethicone.

Supporting ingredient
Listed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.

May suitClimate-sensitive or frizz-prone hair
A surface film slows how quickly humidity reaches the cortex, which is what limits swelling-driven frizz in damp air.

May suitFrizz-prone, damaged, or high-friction hair
Amino-functional silicone carries a positive charge, so it binds where the cuticle is worn rather than coating evenly. Damaged areas get most of it.

May suitMaximum-hold styling
Film formers are what hold a style: they dry into a connected film across the strands so the shape resists movement.

- conditioning agent
- film former
▾Below about this point, order stops being meaningful — these are typically used at 1% or less.
5 Triethanolamine

General function
A base used in trace amounts to neutralise acidic polymers so a gel thickens.

Estimated lower-concentration zone
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.

DependsFrizz-prone, damaged, or high-friction hair
pH adjusters are how a formula is brought to a chosen acidity, and an acidic formula keeps the cuticle lying flatter than an alkaline one. Which way this one moves the pH depends on the formula, and the finished pH is not on the label.

PubChem
- pH adjuster
6 Phenoxyethanol

General function
The most common modern preservative; it keeps the product free of bacteria and mould. It sits well below 1% of the formula.

Estimated lower-concentration zone
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
PubChem
- preservative
7 Carbomer

General function
A thickener that turns a liquid into a clear gel. It also contributes a light hold.

Estimated lower-concentration zone
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.

May suitClimate-sensitive or frizz-prone hair
A set polymer film is a physical barrier to humidity, so a style keeps its shape longer in damp conditions.

May suitMaximum-hold styling
Synthetic film formers dry into a continuous film, which is what holds a shape against movement and against humid air.

DependsBuild-up-sensitive routines
Some acrylate copolymers rinse with water and some need a detergent; the label alone does not say which one a formula used.
- thickener
- polymer

8 Polyquaternium-4

General function
A cellulose-based hold polymer used in gels and sprays for flexible set.

Estimated lower-concentration zone
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.

May suitCurls or waves needing flexible hold
Cationic polymers hold a curl loosely and stay soft, which is why they turn up in definition products rather than firm-hold ones.

May suitFrizz-prone, damaged, or high-friction hair
A cationic polymer stays on the hair through rinsing, which is what keeps static and combing friction down after the wash.

May suitMaximum-hold styling
Film formers are what hold a style: they dry into a connected film across the strands so the shape resists movement.
- conditioning agent
- film former
- polymer
9 Potato Starch Modified

General function
A modified starch. It soaks up oil and water and leaves a dry, slightly grippy feel, which is what puts starches in dry shampoos and texture products.

Estimated lower-concentration zone
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.

May suitFine or easily flattened hair
Adds grip and body with no oil attached, which is what lifts fine hair at the root instead of weighing it down.

DependsMaximum-hold styling
Starch gives texture and grip rather than a set film; firm hold usually needs a polymer alongside it.
- starch
- absorbent
10 Hydroxypropyl Guar

General function
A modified guar gum used to thicken and give a slippery, cushioned feel.

Estimated lower-concentration zone
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.

May suitCurls or waves needing flexible hold
Gums thicken and set soft, which gives definition that bends rather than a rigid cast.

May suitMaximum-hold styling
A styling polymer dries into a film across the strands, which is what makes a shape hold instead of relax.
- gum
- thickener
- polymer
11 Behentrimonium Chloride

General function
A positively charged conditioning agent that binds to damaged, negatively charged spots on the hair. It is the main detangling ingredient in most rinse-out conditioners.

Estimated lower-concentration zone
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.

May suitFrizz-prone, damaged, or high-friction hair
A cationic conditioning agent: it binds to the damaged, negatively charged parts of the cuticle and lowers combing friction there.

DependsBuild-up-sensitive routines
Substantive by design. A routine with no detergent wash gives it nothing to leave with.

DependsVery dry or highly damaged hair
Every detergent removes some sebum along with the product it is there to wash out. Which detergent it is matters more than that there is one.

International Journal of Cosmetic Science

- cleanser
12 Arginine

General function
An amino acid that holds water and carries a positive charge, so it is drawn to damaged spots on the strand.

Estimated lower-concentration zone
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.

May suitVery dry or highly damaged hair
Amino acids are the smallest protein fraction and bind water as well, so they add far less stiffness than a hydrolysed protein does.

DependsClimate-sensitive or frizz-prone hair
A humectant follows the air: it holds water in humid conditions and can give it up in very dry ones. Climate decides what it does more than the label does.

DependsProtein-sensitive hair
The lightest option in the protein family, but still protein — worth watching if protein reliably stiffens your hair.

14 Isopropyl Alcohol

General function
A fast-evaporating alcohol used as a solvent and to speed drying. Well down the list it is a processing aid; near the top it can leave hair feeling dry.

Estimated lower-concentration zone
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.

May suitFine or easily flattened hair
Evaporates on contact, which is how a spray sets almost instantly and leaves no weight behind it.

15 Cetrimonium Chloride

General function
A quick-acting conditioning agent that reduces static and combing force. It also helps keep the formula stable.

Estimated lower-concentration zone
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.

May suitFine or easily flattened hair
The C16 quat binds mostly by charge rather than by chain, so it deposits measurably less than the C22 ones. Less deposit is less conditioning and also less weight, which is usually the trade fine hair wants.

May suitFrizz-prone, damaged, or high-friction hair
A cationic conditioning agent: it binds to the damaged, negatively charged parts of the cuticle and lowers combing friction there.

20 Citric Acid

General function
Used to bring the product to a slightly acidic pH, which helps the cuticle lie flat. It is almost always near the end of the list.

Estimated lower-concentration zone
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.

May suitBuild-up-sensitive routines
Holds hard-water minerals in solution so they rinse away instead of depositing on the hair.

May suitFrizz-prone, damaged, or high-friction hair
The acid side of pH adjustment, and the reason it matters is measured: alkaline formulas raise the fibre's surface negative charge, increase friction between strands and lift the scales, while lower-pH ones do the reverse.

May suitGray, silver, or brass-prone hair
Where a warm cast comes from water minerals rather than from the hair itself, holding those metals in solution is what removes it.

How we work this out

3.4 oz is the size stores list most often; every comparison on this page is made at it. Other sizes are shown in the Sizes row and the store list.
Seen at $45.99 is the price we have observed for the 3.4 oz. We need three stores before we call a price commonly seen.
About $7 is what leave-ins typically cost at this size. Too few of the products that do the same job carry a price for us to draw a good-value line.

How to read this

We look at the first 10–15 ingredients and what they do in a formula — not marketing. If the list doesn't speak to a claim, we don't assume.

How this page was made

Everything above is generated from our researched product record — identity, the ingredient list as printed, the brand's own claims, dated price observations, and review themes written in our researchers' own words. No part of this page is written per product.
The value band is a fixed label over two stored numbers: this product’s cost per ounce as a percentile of every product of this type we have priced, each at the size it is most often sold in, and how many products we score as doing the same job cost at least a quarter less per ounce.
Both scores out of ten are defined on this page. The formula score is completeness for the job, computed from a fixed per-format checklist shown beneath the gauge; the price score is cost per ounce against every product of this type we have priced.
The "Is this right for you?" panel reads only your own consultation answers, and it applies exactly the filters our recommendation engine applies. It is computed when you load the page and is never stored on it.
4 sources consulted for this product (0 manufacturer or regulatory, 0 retailer, 4 editorial), last checked 2026-09-17.
Ingredient references are linked for 14 of 22 product-aware annotations on this page. Fit notes are conditional formulation guidance, not a conclusion about the finished product or about you.
We have not tested this product in a lab and we do not physically test your hair. Formula readings come from the ingredient list; behaviour claims are labelled as the brand's.
Ingredient order tells you relative amount only above roughly 1%. Prices are observations on the dates shown and change without notice.
Ingredient names link to our ingredient library, where each entry shows what it does, which product types use it, and where it usually sits on a label across everything we have researched.
